EXTENSION-TABLE.

$$PEGIFICATION forming part of Letters Patent No. 726,838, dated May 5, 1903.

Application filed September 6, 1902. Serial No. 122,372. (No model.)

T0 at whom it may concern:

Be it known that I, JACOB F. ARNOLD, a citizen of the United States, residing at Massillon, in the county of Stark andState of Ohio, have invented a new and useful Extension-Table, of which the following is a specification.

My invention relates to tables which, are extended at the ends and in which the extension-boards aretelescoped or nested onthe extension-slides in the table proper when the same is contracted; and the object of my-invention is to provide a variable'connection between the extension-boards and the extension-slides, so the boards can be raised and lowered onthe slides and moved along-the same for the ordinary operation of the table and also so the boards can be removed from the slides without detaching any of the parts of either. I accomplish this object by the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of part of a table, showing the nested extension-boards'in one end in section; Fig. 2, a similar view showing the extension-slides on one endfully extended; Fig. 3, a similar view showing the extension-boards raised from the extensionslides; Fig. 4, a similar view showing the extension-slides contracted to close the extension-boards against the table proper; Fig. 5, a detached perspective view of the connecting-bracket, and Fig. 6 a detached perspective view of part of the extension-slide.

The extension-slides I operate a sufficient distance below the table-top 2 to permit the extension-boards 3 and 4 when they are lowered on the slides to pass freely under the table-top when the table is closed.

In the extension-slides are provided the holes or sockets 5, which are preferably inclined and round in section, so they can be formed by boring. One side 6 of the slide is extended upward, from which extension the flange 7 extends part way over the mouths of the sockets, under which flange is formed the channel orgroove' 8. The notches 9 are formed in the flange 7, which'notches preferably correspond in shape to the section of the sockets, but are located away from the line thereof,preferably a short distance to the rear.;

. The connecting-bracket 10 is attached on the under side of the extension-board, which bracket has the depending arms 11, which arms are inclined to extend downward and operate in the socket 5. The shanks 12 of the arms are arranged to pass freely along the edge of the slide-flange7, and the heads 13 are formed on the lower ends of the arms, the parts 14 of which heads project under the flange 7 and are adapted to travel in the slide-groove 8. j

The heads 13 can be formed to correspond in shape with the section of the sockets 5, as shown by broken lines in Fig. 5, or they are formed to correspond with only part of this section, as illustrated, by which correspondonce ofshape the armsareguided and steadied by the sockets.

The arms of the extension-board brackets are normally located in the sockets of the slide; but when the boards are elevated the arms are withdrawn from'the sockets. In this operation the projecting part of the armhead strikes the under side of the slide-flange, "and the board can then be moved along the slide, in which movement the projecting part travels in the slide-groove, and as soon as the socket is cleared the arm-head rests firmly on top of the body of. the slide.

If it be desired to remove the extensionboard from the slide, the board is moved rearward untilthe projecting part of the armheadsregist'er with the flange-notches, when the connecting-bracket can be disengaged from theslide.

I prefer to make the connecting-bracket out of a stiff sheet metal and bent in the form illustrated; but any other form of bracket having a projecting head, as described, will serve as well.

What I claim as my invention, and desire to secure by Letters Patent, is.

1. The combination of an extension-table slide, a socket in said slide, there being a flange on the slide overhanging part of said socket and a groove under said flange, an extension-board on said slide, and an arm depending from said board and operating in the to socket, there being a head on said arm projecting under the flange and adapted to 011* crate along said groove, and a notch in said flange adapted to pass said head.

In testimony whereof I have signed my name to this specification in the presence of 15 two subscribing Witnesses.
